Definitions

  • the invention relates to bonded pressure-resistant glass bodies made of two hemispheres with or without a cylindrical connecting piece for oceanographic use, and to a method for their production and their use.
  • the invention relates to an oceanographic glass case formed from two hemispheres, with or without a cylindrical connector, arranged to form a spherical body, the outer surfaces of which are smooth in any direction.
  • the glass parts which form the pressure-resistant glass body are glued together, so that they can no longer be displaced relative to one another.
  • oceanographic instrument housings which are constructed from two glass hemisphere assemblies. They have long been used in oceanographic research when used as floats and / or instrument housings.
  • US Pat. No. 3,563,089 describes an oceanographic instrument housing composed of two glass hemispheres and a matching protective basket, the glass hemispheres as well as the protective baskets having access openings through which measuring devices or the like can be introduced.
  • the two glass hemispheres are all-round protected by a protective basket.
  • the flat end faces of the glass hemispheres are each in grooves in the protective basket, so that when the circular openings of the two hemispheres are joined together, the protective baskets and not the ones Glass hemispheres come to lie directly on top of each other.
  • the connection of the two glass hemispheres is first made by means of clips and then securely fixed by creating a vacuum inside the sphere.
  • the smooth end surfaces of the glass hemispheres in the grooves of the protective cage are lubricated in a suitable manner, for example with a silicone grease.
  • a bead is applied on the outside at an angle between the glass hemisphere and the protective cage.
  • the seal between the two superimposed protective basket surfaces is also made using a sealing ring that sits in a groove.
  • a disadvantage here is in particular the high workload with many individual work steps and the additional material expenditure for the outer protective cage.
  • seals with sealing rings always show a certain degree of unreliability.
  • U.S. Patent 3,587,122 describes a glass oceanographic round instrument housing. This patent is based on two glass hemispheres that are fitted directly with their semicircular openings. To ensure a secure seal, the two matching surfaces must be ground flat to ⁇ 0.001 inch ( ⁇ 4 ⁇ m). The sealing at the equatorial seam is then carried out by applying a silicone grease to these surfaces. Hose clamps are carefully applied to prevent the hemispheres from moving against each other. A vacuum is then created. The disadvantage here is that the glass balls break, triggered by water penetrating through the silicone grease at high external pressure.
  • the above-mentioned US patent now proposes to omit the silicone grease, that is to say to bring the two surfaces directly onto one another.
  • the required sealing is then carried out by applying a non-hardening material to the outside of the entire equatorial seam and then cover this material with an adhesive tape. So water can no longer penetrate through the seam.
  • FIG. 1 a section through the two hemisphere halves of the glass body according to the invention, perpendicular to the equator,
  • Figure 2 an enlarged section of the vitreous envelope in the
  • Area in which the two glass bodies meet with their smooth surfaces, 3 shows a section perpendicular to the equator of the hemispheres through a special embodiment of the glass body according to the invention, the two glass hemispheres being connected to one another via a cylindrical glass body and
  • FIG. 4 shows a section through a further embodiment of the glass body according to the invention, wherein the zylinderfb 'glass-shaped body is integrally formed directly on one of the two glass hemispheres.
  • the equator seam 6 can be provided from the outside by an elastic sealing compound 7, which is covered with a tape 8 his.
  • the contact surface 4 on the end face of the hemispheres is advantageously a normally ground surface, which preferably has a small chamfer 9.
  • FIG. 3 Another special embodiment is shown in FIG. 3.
  • the two glass hemispheres 1 and 2 are connected to one another via a, preferably cylindrical, glass body 10 in the manner according to the invention.
  • FIG. 4 shows a special embodiment of the glass body 3 according to the invention with cylindrical glass body 10. It is possible according to the invention to form the preferably cylindrical glass body 10 on one end face side 12 directly onto the end face 4 of one of the two glass hemispheres 1 or 2 according to the invention. As a result, only an adhesive layer 5 is again obtained between the end face 4 of the second glass hemisphere 2 or 1 and the end face 12 of the integrally formed cylindrical glass body.
  • distances a and b which characterize the size of the glass hemispheres (distance a is the radius of the glass hemispheres) or the cylindrical glass body used according to the invention (distance b corresponds to the height of the cylindrical glass body), can be chosen as desired.
  • the two distances a and b are preferably in the same size range.
  • A b is particularly preferred.
  • the wall thicknesses of the hemispheres 1, 2 and the cylindrical body 10 are irrelevant for the adhesive. These are only important with regard to the compressive strength.
  • glass bodies with a diameter (2 * a) of 200-600 mm and a wall thickness of 7-20 mm are preferably used.
  • the glass bodies according to the invention are pressure-resistant up to at least 700 bar and permanently resistant to sea water.
  • the production of the glass body takes place in comparison to the production known from the prior art in fewer work steps (only with a normal ground surface on the end of the hemisphere or the cylindrical body, without fine grinding) and does not require a system for generating a vacuum in the assembly Purpose of fixing the glass body. This saves manufacturing costs.
  • the lower number of operations reduces the likelihood of damage to the glass surface during the manufacturing process.
  • surface injuries lead to glass breakage during the use of the glass body. This significantly improves the operational reliability of the systems in use.
  • the glass bodies are permanently glued together.
  • the type of adhesive used here is not particularly restricted. However, it must withstand the pressure corresponding to the depth of use (preferably 700 bar), be resistant to aqueous media, in particular seawater, and show sufficient adhesion to glass.
  • the glass bodies described are suitable as buoyancy balls, for example for oceanographic systems, and for use for the one-time installation of Devices, instruments and energy supply systems in oceanographic use. Deployment depths of up to 7000 m are preferred.

Abstract

L'invention concerne des corps en verre (3) à l'épreuve des pressions, composés de deux demi-sphères (1, 2) avec ou sans pièce intermédiaire cylindrique (10) et dotés de surfaces complémentaires (4) mises en contact l'une avec l'autre, de telle façon que les surfaces extérieures au niveau d'un cordon soient lisses et forment une surface plane. Les éléments en verre sont assemblés de façon définitive par collage avec une colle durcissante appliquée sur ces surfaces complémentaires (4). Un cordon de colle (6) produit, par exemple, par une colle durcissant à la lumière ou à la chaleur peut être recouvert d'une matière d'étanchéité durablement élastique puis d'une bande et/ou d'un ruban. Les corps en verre selon l'invention se distinguent par leur mode de production simple et leur sécurité d'exploitation en cas d'utilisation dans le domaine océanographique.
